Answer:
mass of Zn = 77.0 g
Explanation:
In the sample you have the same moles of Zn and Ga.
The formula for moles is:
Where MM: Molar Mass or Atomic Mass for elements
AM(Ga) = 69.723 amu
AM(Zn) = 65.38 amu
moles of Ga = 
mass of Zn = 
Answer: Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil.
